Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crystal packaging, in particular to a fixing device for crystal packaging. BACKGROUND

[0002] In the semiconductor industry, the packaging of crystals is a key step to protect chips from the external environment, realize electrical connection and heat dissipation. During the packaging of crystals, the accurate fixing of crystals is crucial for subsequent welding, testing and the performance of the final product. When fixing the crystals, a fixing device is used.

[0003] At present, the fixing device for crystal packaging has a fine adjustment mechanism at the bottom of the fixing structure, which can make small adjustments to the fixed crystal in front, back, left and right. However, during the adjustment process, manual or motor-driven adjustment is generally used. Regardless of the driving method, the driving is usually achieved by rotating the threaded rod structure. However, the threaded rod structure is prone to loosening during actual use, which affects the fixing effect of the fixing device and reduces the stability of the crystal during packaging. In addition, the lack of effective flexible clamping structure on the current fixing device for crystal packaging leads to damage to the crystal during clamping and fixing, thus reducing the yield during crystal packaging. Moreover, although some fixing devices use a manual rotating threaded rod method to move the clamping plate and achieve the fixing of the crystal, the manual fixing device has a low cost. However, it requires many turns of the threaded rod during rotation, thus reducing the fixing efficiency of the fixing device. SUMMARY

The sliding rod and external spring of the sliding rod can provide good clamping force and flexibility when clamping the crystal, thus avoiding damage to the crystal during clamping and fixing, thus improving the yield during crystal packaging. The limiting assembly and rectangular slot can improve the fixing efficiency of the fixing device by moving the Z-shaped auxiliary rod to the left without rotating the threaded rod.
